Great season. Had me invested and excited pretty consistently throughout. Only comment the last episode is it felt like it could have been 2-3 episodes or started 1-2 episodes earlier.
Steve was kidnapped, there was a falling out with his partner, the vice minister went to Pablo's prison to try to cut a deal, and the prison was raided. A lot of compelling plots lines that get introduced and tied up in this episode - a bit hastily I think.
The run time was 45 minutes so even adding another 10-15 minutes of screen time may have done the trick. While I love the action and movement, the episode could have emphasized the stress and anxiety of the situation by slowing things down.
The way the kidnapping was presented seemed sloppy as well - we see Steve kidnapped then 15 minutes later in the episode we see him at the embassy and he recounts the story in flashback. It doesn't maximize the drama or the gravity of the situation. I think by not addressing it it's supposed to be more dramatic, but I don't think it worked.
The final episode sets itself up for another season - all out war between Pablo and the Columbian government. If there was a season two I'd tune in, but I don't think it could possibly touch as many dynamic stories as season one, which handles the genesis, rise, and fall of Pablo.
